Abstract (en)

The impeller (1) is provided with a disk (11) that rotates about an axis line (O), and a plurality of blades (12) provided at intervals around the circumference of the disk (11). Defining the blade angle (²) of the tip of each blade (12) as a first blade angle, the tip has a constant-tip-angle area in which the first blade angle is constant from an inlet where fluid flows in toward an outlet side, and an increasing-tip-angle area that is continuous with the outlet side of the constant-tip-angle area and that has a gradually increasing first blade angle towards the outlet.
